IMPROVED COOLERFOR BEER, 80C.

Speciiication forming part of Letters Patent No. 57,900, dated September 1'1, 1866.

souri, have invented a new Cooler for Beer andother Fluids; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of this invention consists in discharging the fluid to be cooled down through a cooling-chamber inra shower of distinct drops or very small streams. The cooling-chamber is to be packed on all sides with ice, and is also to have a continuous current of cold air passing up through it. It is furthermore to have a large number of pipes passing through it, the said pipes being brought to so low a degree of temperature by the surrounding packing of ice that their immense surface will tend to cool the fluid passing over them very rapidly. The disposition of these pipes is such that the fluid passing down through the cooling-chamber will strike them and diffuse itself over the vast amount of area they present.

To enable those skilled in the art to make and use my improved cooling apparatus, I will proceed to describe its construction and operation.

Of the accompanying drawings, Figure l represents a side elevation of the said cooler. Fig. 2 is a half -plan and half -section; and Fig. 3 is a sectional elevation bisecting the apparatus.

' A is a central circular chamber, to be lled with ice. This ice-room is to be surrounded with an annular cooling-chamber, B, formed between the vertical circular walls a b, and this cooling-chamber is itself surrounded by an ice-chamber, C, formed between the walls b c. The wall c, forming the outer wall of the cooler, may be made either single or double thickness. There are numerous tubes, B', passing horizontally through the chamber B and attached to its walls a b. These allow cold currents of air to pass through them from the chamber A nto chamber C, or in an opposite direction, as the case may require.

The bottom Af, on which the chambers A B O are erected, forms the top plate of a sub icevault, A2, which is surrounded by the walls c', and rests on its bottom c2. As the ice which fills the chambersACisliable to becomemelt'ed,

and thereby ll the said chambers with water,

, and A3.

The fluid 'to be cooled in this apparatus is to be placed in the annular chamber or basin D, directly above the chamber B. The bottom d of this basin is to be perforated with small holes, as shown in the drawings. Through these small orifices the iluid will run down in very small streams or in a shower of drops, and as it descends through the cooling-chamber B, it will strike and diffuse itself over the tubes B', and then drop down from one to another of these tubes, until it reaches the chamber B2, whence it will be drawn off through the discharge-pipe D.

The basin D should not rest down tightly on the walls a b but a space should be left there to allow the air that rises through the chamber B to escape. A continuous current is fed into the chamber B2 through the airsupply pipe E, where the air so fed in is reduced to a very low temperature by means of ice placed therein. From the chamber A2 the air thus cooled is conducted up into the chamber B2 through the tubes E. These tubes extend above the floor Al sufficiently' to prevent the iiuid which may restthereon from running down through them into the vault or chamber A2. The tops of them are capped with hoods e, to prevent the dropping uid from dropping into them.

By the use of this apparatus beer may be brewed in summer.

There should be a door, F, made in the,

wall c', for the purpose of supplying ice to the vault A2. p
